Instrumentální metody stanovení mikroplastů

Abstract

This bachelor's thesis focuses on instrumental methods for determining microplastics in aquatic environments. The theoretical part of the thesis covers the history and development of plastics and microplastics, their recycling, environmental impact, and instrumental methods used for assessing microplastic pollution. The practical part of the thesis is dedicated to detecting and identifying microplastics in various types of water, specifically surface water from the Bečva River, treated wastewater from a municipal wastewater treatment plant, and tap drinking water. This work provides insights into the prevalence of microplastics in the environment and describes the process of their determination using FTIR spectroscopy on water samples. It can be concluded that microplastics were detected in all tested types of water, and the results, including particle type, color, and identified material along with their evaluation, are presented in the practical section of the thesis.
